I have a Motorola rokr dual band phone and I need to flash it to tri band. How do I do this?

If you have a Motorola ROKR Z6m (Slider) this phone's radio frequencies are factory pre-set to dual band (CDMA 850Mhz / 1900Mhz) . As such, there is no way to flash it to make this a tri-band phone.

If you are in the United States you only need a dual band phone as these two frequencies are the only ones used. The only time you would ever need the 900Mhz frequency is if you are traveling internationally. Otherwise, you would never use or need the 900Mhz frequency.

If you are planning to travel internationally, you would need to purchase a different phone.

Invalid Sim

If your phone is locked to your original sim card, you will not be able to use any other. contact your provider and see if it is in fact locked. Many phone providers lock their phones.

Motorola frequances

Google search indicates that the Motorola GP300 is a portable
walkie-talkie UHF Transceiver. The exact model gets no hits.

The UHF frequency band ranges from 300MHz to 3GHz,
or 1 meter down to 10 centimeter is wavelength.
This includes some analog cellphone bands.

The actual capability of the transceiver
(i.e. The channels or sub-bands) probably depends on
a finite set of crystals installed within the transceiver,
and licensed to a particular end user/agency.

Your first step is to contact Motorola, and to get the
user manual, complete with full specifications.

Once you know, what the capabilities are, you will have
a better idea of what you want you can or want to listen to.

Also be careful not to transmit in somebody else's band
(any band without a license, pretty well), or
you can find yourself in a pile of legal trouble.

Even eaves-dropping on some other person's
conversation may be illegal in some circumstances.

Hope this gets you started
